First of all i want to congratulate you for this initiative and for sure it's really sounding as Selfless Contest and in my opinion these kind of contests can really increase the Engagement and it will going to create an healthy competition where people will going to try to produce their Freewrite pieces.
And i agree with your point and that is, this post can prove as an "Brainstorming" aspects where we are not thinking about the overall posts but we will going to meditate with our words and all the words will flow in one run.
And that picture is really awesome and i can see an Fun Aspect and that is, that Deer is reflecting as going for an walk.
Wishing you an great day and stay blessed. 🙂
